Application February 25, 1942, Serial No. i32,212

8 Claims. (01. 299-88) My invention relates to atomizers and refers particularly to devices ofthe general character described, in which a liquid is retained in, and carried by, an absorbent material.

Atomizers of this character possess many advantages over those in which a mass, or body, of free liquid is present, over or through which air is forced, among which are the freedom from spilling of the liquid, the better atomization obtained because of the passage of air over a large surface of liquid, a reduction in loss of liquid by evaporization, and the production of increased and improved atomization by presenting a more complete and constant mixture of air and liquid at the point of atomization.

One disadvantage experienced in atomizers of this general character is the tendency of the absorbent material to pack over the exit opening, thus preventing the free passage of the air and liquid mixture through the exit opening, resulting in uneven and unsatisfactory atomization.

Another disadvantage experienced in these atomizers is that when the mixture of air and liquid is forced directly through an exit opening of the casing connected'directly with the main passageway in which the air and liquid are commingled, the spread of the atomized mixture is insufficient and the mixture has a tendency to be emitted in the form of a stream.

Another disadvantage in devices of this character is that as the passage of air through the device, when operated, is quite rapid, the last portion of the air has not had sufficient time to extract the proper amount of liquid from the absorbent material, and hence there is a deficiency of liquid at the exit point, producing an uneven spread and composition to the atomized mixture.

My invention relates to atomizers in which the above-mentioned and other disadvantages of devices of this character have been overcome, and which produce even and constant mixtures, which, when atomized, produce superior atomization with constant and greater spread, all of which will be evident upon a consideration of my specification and drawing, in which modified forms of my devices are clearly shown and in which similar parts are designated by similar numerals.

Figure 1 is a vertical section taken through one form of a device of my invention.

Figure 2 is a section taken through the line 2-2 of Figure 1.

Figure 3 is a top plan view of one form of a cover disk for use in my devices.

I Figure 4 is a perspective view of one form of a mass of absorbent material adapted for use in my devices.

Figure 5 is a top plan view of an exit disk of my devices.

Figure 6 is a fragmentary vertical section taken through a modified form of my devices.

Figure 7 is a vertical section taken through a modified form of a device of my invention.

Figure 8 is a section through the line 88 of Figure 7.

The particular form of a device of my invention shownin Figures 1, 2, 3 and 5 comprises a cylindrical casing having the side l0, one end of the casing having an end member I l with a centrally positioned opening I2, the other end of the casing being open.

Positioned within the casing and abutting upon the inner face of the end member I I is a disk or spacer 13 having an opening l4 therein of smaller diameter than the diameter of the opening i2 of the end member II. This disk l3 may be of any, suitable material such as fiber; glass cloth, or fine wire mesh and'I have found paper particularly adapted for this purpose.

Positioned within the casing and abutting upon the'disk I 3 is an elongated octagonal member I5 extending towardv the openend of the casing. This octagonal member is composed of any suitable liquid absorbing material and I have found felt to be particularly suitable for this purpose. A longitudinal opening [6 extends through the absorbent member IS in alignment with the opening Id of the disk l3, the opener l6 being of greater diameter than that of the opening M.

It will be noted that there is thus formed four longitudinal channels, or spaces, l1, [1, between the casing side l0 and the faces of the absorbent member I5.

Positioned upon the outer exposed face of the absorbent member I5, is a cover disk l8 which may or may not be of absorbent material, but if it is of non-absorbent material it should have the radiating gutters, or recesses, l9; l9.

This disk l8 has a centrally positioned opening 20 in alignment with the opening l6 of the absorbent member l5.

The outer end of the casingcarries a compressible rubber ball 2|, the thickened end 22 of which is positioned within the outer end of the casing. This thickened end portion 22 has a longitudinal opening 23 in alignment with, and of a greater diameter than, the opening 23 of the disk cover l8. I

One way of charging thisdevice with a liquid is to depress the ball 2|,insert the forward end of the device into the liquid and release the pressure upon the ball, thus driving a quantity of liquid through the openings I2 and I 4 into the opening Hi from which it is absorbed by the absorbent member I5.

In operation, the ball 2| is pressed thus forcing some of its air content through the opening 23, the radiated passageways l9, l9 through the spaces [1, l1, l1, l1, between the disk l3 and the end member I l, and outwardly through the opening I2 in the form of a spray. The remainder of the air passing through the opening 23, the opening 20, the opening it and the openings l4 and I2 in the form of a spray. Some of the air may also pass between the disk l3 and the absorber I shape, number, arrangement or material of parts material l5. All of this air in passing through the device passes over the absorbent material and carries a proportion of liquid with it to produce a fine spray effect at the exit opening.

The modified form of a device of my invention shown in Figures 2, 4, 7 and 8 is similar to the previously described form of my device, as indi cated by corresponding numerals, but differs from it in the following manner. This modified. form of my device has a plurality of disks, or spacers, l3, 13, I3, having aligned holes I4, I 4, k5 through them. These disks may be made from various materials which may, or may not be absorbent. The absorbent member of this device consists of a plurality of round disks 2 24 of absorbent material having aligned openings therethrough. This form of my device does not have a free end disk cover, the portion 22 of the rubber ball 2! abutting upon the free face of the last absorbing disk. 24.

In the operation of this form of my device the air passes from the ball 2| through the opening 23, the openings l6, l6, theopenings I4, Id, and the opening l2 in the form of a fine spray.

Figure 6 illustrates a. modified form of'a device of my invention, adapted for the charging of the absorbent material with a liquid without the necessity of inserting the exit end of the device into the liquid.

In this form of my device an opening is made A in the side member In of the casing, which is fitted with the extended threaded neck 25, which is adapted to thread with the neck 26 of the liquid container 21.

When it is desired to charge the absorbent ma- '1 terial H3, or the device is shaken to allow some of the liquid to be splashed into the absorbent material. When sufficient liquid has been inserted into the device, the liquid container is removed and a suitable closure is threaded upon the device neck 25.

If desired liquid'may also be introduced by removing the collapsible rubber ball device and pouring liquid through the thus produced open end of the casing.

While I have shown my device with a collapsible rubber ball as a means for producing the atomizing effect, it is evident that other suitable means may be employed for this purpose.

It is to be noted that a valuable feature of my devices s that the absorbent material not clog up, or partially close, the exit openings in the disks at the exit end, thus being accomplished by having the opening in that portion of the absorbent material abutting upon a disk of greater diameter than the disk opening;

as shown and described as these are given solely for the purpose of clearly describing the devices of my invention.
